    OEM Komatsu Hitachi Excavator Pins And Bushings Replacement

    OEM High Quality Mechanical Engineering Vehicle Excavator Parts Bucket Bushing


    Product Description

    SN-H Steel Bushing

    SN-H Steel Bushing
    The inner surface of SN-H steel bushing bearing is processed with various types of oil grooves, which improves the surface hardness and wear resistance after heat treatment. It is suitable for heavy-duty joint parts of construction machinery such as excavators, rotary drilling rigs, large loaders, wall grab and so on.
    The steel bushing bearing of our company is based on 45#, 40Cr, 20CrMo, GCr15 and other materials. From raw materials to finished products, each process is strictly controlled to ensure the product quality. It produces bushing with high wear resistance, high surface hardness and strong internal toughness.

    blind hole oil storage steel bushing

    blind hole oil storage steel bushing
    The inner surface of the blind hole oil storage steel bushing is sprayed with molybdenum disulfide, which has the advantages of
    low friction coefficient and good wear resistance, and can work under the condition without oil or with little oil. Products are
    widely used in construction machinery, heavy duty high load equipment.
    Process: Multipurpose furnace carburizing
    Thickness of carburized layer:1.5-2.0mm

    Product Advantages
    The inner wall of the bushing is evenly distributed with blind holes with conical cross-section.
    The lubricating oil wedge is formed naturally during the grinding process of the inner hole of the bushing
    The oil storage capacity of oil pocket is large, which is 3~5 times of that of ordinary oil tank and can be free from maintenance for a long time.
    The oil pockets are evenly distributed on the inner wall, and the center distance of the oil pockets in the circumferential direction is fixed. No matter how large the bushing is, it only needs a small rotation angle to fill the inner surface of the bushing with the oil cloth, without lubrication dead area.
    The oil pockets evenly distributed in the inner holes do not damage the bearing capacity of the inner wall of the bushing and prolong the service life of the bushing.
    Material: 20CrMnTi, 20CrMo and other low carbon alloy steels Surface treatment: Molybdenum disulfide spraying

    SN-X Mesh steel bushing

    Due to the combination of double surface treatment and special surface morphology, the mesh bushing has excellent wear resistance and seizure resistance. This cross hatch morphology provides a grease reservoir in the load area and can remove abrasive particles. They are suitable for working under harsh working conditions: High pressure, wear, impact and corrosion. Mesh sleeves are alternatives without cross-hatches. They provide excellent performance under high static loads (low dynamic pressures) and small oscillations (wear resistance and seizure resistance...)

    SN-B Bimetallic composite self-lubricating bushing

    The bimetallic self-lubricating graphite copper bushing is based on low carbon steel, and the inner surface is Tin Phosphorus Bronze, the thickness can be customized 0.5-5mm. The ZCuSn10P1 tin-phosphorus bronze has high hardness and wear resistance. It can be used to manufacture parts that work under heavy load, high speed and high temperature, and the copper bushing is subject to strong friction. The surface of the bimetallic self-lubricating graphite bushing is inlaid with a special formula of solid lubricant at a certain angle and density, which is precisely processed, so that the copper bushing has the advantages of high wear resistance, high hardness and high toughness.

    The bimetallic self-lubricating graphite copper bushing is a novel lubricating bearing with the characteristics of metal bearing and self-lubricating bearing. It is loaded by metal matrix, and the solid lubricating material with special formula plays a lubricating role. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance and strong self-lubricating capability. It is especially suitable for occasions that are difficult to lubricate and form oil membrane, such as heavy load, low speed, reciprocating or swinging, and it is also not afraid of water erosion and erosion of other acids.
